Abstract
<p>SPEX is a software package for fitting astrophysical X-ray spectra. It has been&nbsp;developed since the 1970s at SRON Netherlands Institute for Space Research. SPEX is an&nbsp;interactive command-line program for the computation of emergent spectra of optically&nbsp;thin plasmas such as stellar coronal loop structures, supernova remnants (also including&nbsp;transient ionization effects), photo-ionized plasmas, and optically thick plasmas. These&nbsp;model spectra can be fitted to measured X-ray spectra from various X-ray observatories, like&nbsp;XMM-Newton and Chandra. SPEX has been optimized for high-resolution X-ray spectroscopy, which&nbsp;makes it espec...
